Fire-induced spallingConcreteTunnel liningDamageIn this paper, risk is calculated as the probable damage caused by a fire in the tunnel lining. The model is intended to be as simple as possible and still able to reflect the reality. In the first part, focused on probabilistic modeling, the ...
A concrete tunnel structure exposed to fire will deteriorate to a certain degree when the temperature increases in the cross-section. The thermal diffusivity of concrete is low which causes a high thermal gradient close to the exposed surface during fire exposure which results in a gradient of det...

tunnel fireheating ratespallingfire damage rangeWhile fire outbreaks in tunnels are not as frequent as those in other structures, temperature rises up to over 1,000 degrees C within 5 minutes upon the outbreak of a fire in a tunnel due to its semi-closed structure. Temperature rise in a ...
the safety of tunnel structures when subjected to fire, a numerical simulation was conducted to assess the safety of the tunnel under varying stress fields... HP Lai,G Sheng,YL Xie - 《Magazine of Concrete Research》 被引量: 2发表: 2015年 Damage assessment of RC voided slabs experienced ext...
In order to explore the damage and mechanical properties of ballastless track after a fire, the uniaxial compressive strength, shear strength, peak strain, and elastic modulus changes due to temperature were obtained through uniaxial compressive and shear tests of concrete after exposure to high temper...
